Flash Player doesn't send a stream it's publishing using IP multicast. Flash Player will only publish using P2P multicast. however, it can use IP multicast to discover peers on the same LAN, to 1) help optimize the P2P group topology; and 2) to join a group on the same LAN without a connection to a server.
Adobe Media Server can send a stream in fusion mode.
a receiving peer would never re-send the stream using IP multicast. it would only send the stream directly to other peers.
thanks a lot to discribe this
so for ip multicast video receivce a adobe media server must be in the same lan as the clients
not necessarily. Adobe Media Server sends IP multicast packets with a TTL of (if i remember correctly) 64. if your network supports IP multicast routing, then AMS doesn't have to be on the same LAN as the receiving clients.
the IP multicast packets sent by Flash Player (such as the peer discovery packets) are sent with a TTL of 1, so they only work on the same LAN.
